Description
Technical field
The utility model relates to lamp bar mounting structure in a kind of liquid crystal display module.
Background technology
Existing liquid crystal display modular architecture, as shown in Figure 1, normally lamp bar 110 is fixed on support 210, and then be fixed on backboard 410 by support 210, light source 120 on lamp bar 110, as LED light source etc., usually by the incidence surface 311 parallel placement of the exiting surface of light source 120 with light guide plate 310.But existing this set structure, adds the cost of this support on the one hand, the existence of this support too increases the thermal resistance on heat dissipation channel in addition, in addition, due to the existence of light guide plate expanded by heating, distance between this exiting surface and light guide plate is also comparatively difficult to ensure card, easily causes the damage of lamp body.
Utility model content
The technical matters that the utility model solves is: the problem of lamp body radiating effect difference.
The utility model solves the technical scheme that its technical matters adopts: lamp bar mounting structure in liquid crystal display module, comprise backboard, lamp bar and light guide plate, described light guide plate is arranged on backboard, described backboard is provided with recessed ramp structure in the incidence surface side near light guide plate, and the angle between this ramp structure and light guide plate is α; Described lamp bar be arranged on ramp structure domatic on, lamp bar is provided with light source; Also comprise reflector plate, described reflector plate is arranged on the incidence surface side of light guide plate, for the incidence surface from light guide plate after the light reflection launched from light source is injected light guide plate.
Further: described reflector plate comprises a vertical section, described vertical section is corresponding with the incidence surface of light guide plate; After the upper end bending of vertical section, form a horizontal segment, described horizontal segment is parallel with the exiting surface of light guide plate, and blocks on the exiting surface of light guide plate corresponding part.
Further: described vertical section is that the first paragraph of β and second segment form by angle, forms a horizontal segment after the upper end bending of described first paragraph; By the combination of described first paragraph or first paragraph and second segment, light guide plate can be injected after the light reflection launched from light source with the incidence surface perpendicular to light guide plate.
Further: described reflector plate is silver-colored reflector plate or white reflection sheet.
The beneficial effects of the utility model are: by arranging recessed ramp structure on backboard, and on the ramp structure directly install lamp bar, directly dispelling the heat by backboard of such lamp bar, improves forehead lamp bar radiating effect.In addition, adopt this mounting means, light guide plate can not directly contact with lamp bar after expanding firmly, therefore can not cause the damage of lamp bar.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of body mounting structure in prior art;
Fig. 2 is the schematic diagram of the first mounting structure of the utility model;
Fig. 3 is the schematic diagram of the utility model the second mounting structure; ;
Be labeled as in figure: lamp bar 110, light source 120, support 210, light guide plate 310, incidence surface 311, exiting surface 312, backboard 410, ramp structure 420, reflector plate 500, vertical section 510, first paragraph 511, second segment 512, horizontal segment 520.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is further illustrated.
As shown in Figures 2 and 3, lamp bar mounting structure in liquid crystal display module described in the utility model, comprise backboard 410, lamp bar 110 and light guide plate 310, described light guide plate 310 is arranged on backboard 410, it is characterized in that: described backboard 410 is provided with recessed ramp structure 420 in incidence surface 311 side near light guide plate 310, and the angle between this ramp structure 420 and light guide plate 310 is α; Described lamp bar 110 be arranged on ramp structure 420 domatic on, lamp bar 110 is provided with light source 120; Also comprise reflector plate 500, described reflector plate 500 is arranged on incidence surface 311 side of light guide plate 310, for the incidence surface 311 from light guide plate 310 after the light reflection launched from light source 120 is injected light guide plate 310.
Wherein, by arranging recessed ramp structure 420, lamp bar can be arranged on this ramp structure 420 with in the direct gap formed of light guide plate 310, and as shown in Figures 2 and 3, lamp bar 110 is positioned at the below of light guide plate 310, therefore can not be extruded damage because of the expansion of light guide plate 310.In addition, because lamp bar 110 is directly installed on backboard 410, therefore the radiating effect of lamp bar 110 is better.
The effect of reflector plate 500 is reflected by the light that the light source 120 on lamp bar 110 is launched, and then the light after reflection is injected light guide plate from the incidence surface 311 of light guide plate 310; In order to improve light reflectance as far as possible, preferably adopt silver-colored reflector plate or white reflection sheet as reflector plate 500.
In addition, the utility model can adopt the setting of at least the following two kinds reflector plate 500:
The first, as shown in Figure 2, described reflector plate 500 comprises a vertical section 510, and described vertical section 510 is corresponding with the incidence surface 311 of light guide plate 310; After the upper end bending of vertical section 510, form a horizontal segment 520, described horizontal segment 520 is parallel with the exiting surface 312 of light guide plate 310, and blocks on the exiting surface of light guide plate 310 corresponding part.Wherein, the effect of vertical section 510 is mainly applicable to the light that reflection source 120 is launched, and arranges the object of horizontal segment 520, then mainly in order to reduce the loss of light.
The second, as shown in Figure 3, on the first basis above-mentioned, is that the first paragraph 511 of β and second segment 512 form by vertical section 510 by angle further, forms a horizontal segment 520 after the upper end bending of described first paragraph 511; By described first paragraph 511 or first paragraph 511 and the combination of second segment 512, light guide plate 310 can be injected after the light reflection launched from light source 120 with the incidence surface 311 perpendicular to light guide plate 310; By vertical section 510 being arranged to by first paragraph 511 and second segment 512 composition form, its objective is and want to realize the reflection by reflector plate 500, by light to inject in light guide plate 310 perpendicular to the angle of incidence surface 311, and then the incident effect of light can be improved.Certainly, in this case, the parameter such as angle for angle α, angle β and first paragraph 511 and light guide plate 310 needs to determine according to actual conditions; And there is between three certain correlativity.
